Debug
Known issues
gotchaThe output is written to stdout; you must redirect to a file or use the output.
fix
Use shell redirection: graphql-introspection-json-to-sdl schema.json > schema.graphql
affects: >=1.0.0
gotchaThe input JSON must be a valid introspection query result (e.g., from graphql(IntrospectionQuery)).
fix
Ensure the JSON file contains the full introspection result, not just the data part.
affects: >=1.0.0
deprecatedThe package does not support the newer @link directives or federation introspection. SDL output may be incomplete for modern schemas.
fix
For federated schemas, consider using @apollo/federation-introspection or graphql-inspector.
affects: <2.0.0
